Mars - Page 53
Mars is the fourth planet from the Sun in the solar system, known for its reddish appearance due to iron oxide (rust) on its surface. It is often referred to as the "Red Planet." Mars has a thin atmosphere, composed mainly of carbon dioxide, with traces of nitrogen and argon. Its geological features include the largest volcano in the solar system, Olympus Mons, and the deepest canyon, Valles Marineris. Mars has polar ice caps that vary in size with the seasons and is of significant interest in the search for past or present life due to evidence of water in its history. It has two small moons, Phobos and Deimos. Mars is also a focal point for future human exploration and potential colonization.
